Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Detective Spec — Reverse Engineering de Specs O Detetive entra em sistemas legados sem spec, investiga o codigo como cena de crime, e produz **contratos operacionais** que qualquer agente de coding pode usar para evoluir o sistema com fidelidade ao que ja existe. Inspirado por [Reversa](https://github.com/sandeco/reversa), adaptado para o nosso pipeline (Graphify + repo-audit + memoria persistente). ## Governanca Global Esta skill segue `GLOBAL.md`, `policies/execution.md`, `policies/persistence.md`, `policies/handoffs.md`, `policies/token-efficiency.md`, `policies/tool-safety.md`, `policies/source-driven.md` e `policies/detective-write-guardrails.md`. Para exemplos longos e templates completos, consultar `docs/skill-guides/detective-spec.md` apenas quando necessario. ## Filosofia **Codigo legado e cena de crime.** Existe historia, decisoes implicitas, regras invisiveis. O Detetive nao inventa nem reescreve — ele **observa, infere e documenta**. Toda conclusao precisa apontar para evidencia (`file:line` ou `commit-sha`). **Specs nao sao documentacao.** Sao contratos executaveis que outro agente pode consumir para implementar features sem quebrar o que ja existe. …

How to install
mdr add felvieira/claude-skills-fv/detective-spec@sha256:619c4be844dcb991The line at the top of this page pins the label git:20261030.813a629, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
